Thermal energy meters - Part 4: Pattern approval tests

This document specifies pattern approval tests for thermal energy meters. Thermal energy meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The thermal energy meter indicates the quantity of thermal energy in legal units.
This document covers meters for closed systems only, where the differential pressure over the thermal load is limited.
This document is not applicable to:
-   electrical safety requirements;
-   pressure safety requirements; and
-   surface mounted temperature sensors.

Thermische Energiemessgeräte - Teil 4: Prüfungen für die Bauartzulassung

Dieses Dokument legt Prüfungen zur Bauartzulassung für thermische Energiemessgeräte fest. Thermische Energiemessgeräte sind Messgeräte, die dazu bestimmt sind, die Energie zu messen, die in einem Wärmetauschkreislauf von einer als Wärmeträgerflüssigkeit bezeichneten Flüssigkeit aufgenommen (Kühlung) oder abgegeben (Heizung) wird. Das thermische Energiemessgerät zeigt die Menge der thermischen Energie in gesetzlichen Einheiten an.
Dieses Dokument behandelt nur Messgeräte für geschlossene Systeme, bei denen der Differenzdruck über die thermische Last begrenzt ist.
Dieses Dokument ist nicht anwendbar für:
—   Anforderungen an die elektrische Sicherheit;
—   Anforderungen an die Drucksicherheit;
—   oberflächenmontierte Temperaturfühler.

Compteurs d'énergie thermique - Partie 4 : Essais en vue de l'approbation de modèle

1   Domaine d’application
Le présent document spécifie les essais en vue de l’approbation de modèle pour les compteurs d’énergie thermique. Les compteurs d’énergie thermique sont des instruments destinés à mesurer l’énergie thermique qui, dans un circuit d’échange thermique, est absorbée (refroidissement) ou cédée (chauffage) par un liquide appelé « liquide caloporteur ». Le compteur d’énergie thermique fournit la quantité d’énergie thermique en unités de mesure légales.
Le présent document couvre les compteurs pour les systèmes fermés uniquement, où la pression différentielle dans la charge thermique est limitée.
Le présent document ne s’applique pas :
-   aux prescriptions de sécurité électrique ;
-   aux prescriptions de sécurité relative à la pression ;
-   aux sondes de température montées en surface.

Merilniki toplote - 4. del: Preskusi za odobritev tipa

Ta dokument določa preskuse za odobritev tipa merilnikov toplote. Merilniki toplote so instrumenti, namenjeni merjenju energije, ki jo v krogotoku toplotne izmenjave absorbira (hlajenje) ali oddaja (ogrevanje) tekočina, imenovana tekočina za prenos toplote. Merilnik toplote podaja količino toplote v predpisanih enotah.
Ta dokument ne zajema zahtev za električno varnost.
Ta dokument ne zajema tlačnih varnostnih zahtev.
Ta dokument ne zajema površinsko nameščenih senzorjev temperature.
Ta standard zajema samo števce za zaprte sisteme, pri katerih je diferencialni tlak nad toplotno obremenitvijo omejen.
